Is there a way to create a pause between movements in Animation Nodes?
I'm sure there are many ways to create this effect but here is one relatively simple one:



The essential node here is Mix Euler List. For translation you could use the Mix Vector List node.

The Mix Euler List node takes a list of vectors and a value between 0 and 1 (can be higher when Repeat is enabled). If the factor is 0 it will output the first element, if it's one it will output the last one. All values inbetween will result in an interpolated output. (eg. 0.1 will be something between 0° and 90° in the z-axis).

The downside of this approach is that the time intervalls are always the same, but it seems to work in your case. You can animate the time somehow to change the intervalls using the same approach but this can become messy very quickly so I didn't do it here.
